Abstract (en)
An optical test apparatus includes a collimator comprising a dual-fiber ferrule and a collimating lens. The optical test apparatus also includes an optical filter optically aligned with the collimator, a first optical fiber pigtail connected to the collimator at a first bore of the dual-fiber ferrule, a second optical fiber pigtail connected to the collimator at a second bore of the dual-fiber ferrule, and a photodetector in optical communication with the collimator. The optical test apparatus defines a reflection path from the first optical fiber pigtail to the optical filter and from the optical filter to the second optical fiber pigtail and a transmission path from the first optical fiber pigtail through the optical filter to the photodetector.
